Lithium Niobate Modulator Transmitter Module 30 GHz

The LNTM is a high-performance laser transmitter/converter module designed for analog photonics applications spanning 10 MHz to 30 GHz, featuring high extinction >20dB. It integrates a lithium niobate waveguide modulator, a distributed feedback (DFB) laser, and an automatic bias controller. The automatic bias controller eliminates drifts caused by environmental temperature variations or extended operation, having four operation modes: Q+ and Q- for quadrature points with positive or negative slopes, ideal for linear analog modulation, and Min and Max for minimum or maximum points, optimized for pulse generation in digital modulation. Powered by a single 12V DC supply, the LNTM provides a versatile, reliable solution for RF-over-fiber (RFoF) system integration, enabling precise and stable signal transmission.
